Scroll Compressor

Simple Design with 70% Fewer

Parts

Fewer parts than an equal capacityreciprocating compressor meanssignificant reliability and efficiencybenefits. The single orbiting scrolleliminates the need for pistons,connecting rods, wrist pins andvalves. Fewer parts lead to increasedreliability. Fewer moving parts, lessrotating mass and less internalfriction means greater efficiency thanreciprocating compressors. The Scrollprovides important reliability andefficiency benefits. The Scroll allowsthe orbiting scrolls to be in contact inall three dimensions, forming acompletely enclosed compressionchamber which leads to increasedefficiency. In addition, the orbitingscrolls only come in contact with theminimum required force to create aseal so there is no wear between thescroll plates. The fixed and orbitingscrolls are made of high strength castiron which results in less thermaldistortion, less leakage, and higherefficiencies. The most outstandingfeature of the Scroll is that theslugging will not cause failure. Incontrast, the liquid or dirt found in areciprocating compressor may causeserious damage.

Low Torque Variation

The Scroll compressor has a verysmooth compression cycle withtorque variations that are only30 percent of that produced by areciprocating compressor. This meansthe scroll compressor imposes verylittle stress on the motor for greaterreliability. Low torque variationmeans reduced noise and vibration.

Modulating Gas Burner

• EfficiencyThe modulating gas burner operatesas a condensing gas burner for themain part of its operating range. Thisresult in a drastically improvedefficiency (up to 105%) and optimumenergy usage.

• ComfortThe modulating burner adapts theheating capacity to the buildingneed. Modulation of heating capacityresults in continuous operation of theburner at part load. Reduced ON-OFFcycling improves the gasconsumption used during each startup of the burner as well as dischargeair temperature variation.

Temperature uniformity: Control ofthe supply air temperature reducesair stratification effect caused by hightemperature supply air. This result ina better mixing of the supply air withthe air in the room.• ReliabilityFull stainless steel weldedconstruction ensures reliable heatexchanger tightness.

Flame control: Ignition andcombustion controller use a provendirect spark ignition with pre-mixburner technology. This result in aconstant gas/air mix and optimizedcombustion quality over thecomplete operating map.

Drum and Tube Gas Heat Exchanger

• The drum and tube heat exchangeris designed for increased efficiencyand reliability and has utilizedimproved technology incorporatedin the large rooftop commercialunits for almost 20 years.

• The heat exchanger ismanufactured using aluminizedsteel with stainless steelcomponents for maximumdurability. The drum and tubedesign has been tested and passedover 150,000 cycles.

• The negative pressure gas valve willnot allow gas flow unless thecombustion blower is operating.This is one of our unique safetyfeatures.

• The forced combustion blowersupplies premixed fuel through asingle stainless steel burner screeninto a sealed drum where ignitiontakes place. It is more reliable tooperate and maintain than amultiple burner system.

• The ignitor is a gas ignition devicewhich doubles as a safety deviceutilizing a continuous test to provethe flame. The design is cycle testedat the factory for quality andreliability.

• The Trane Voyager Rooftop has, by

far, the best COP in its class. All

performances are Eurovent

certified which provides the

assurance of accurate

performance and common

comparison criteria.

Rigorous Testing

• All of Voyager's designs wererigorously rain tested at the factoryto ensure water integrity.

• Rigging tests include lifting a unitinto the air and letting it drop onefoot, assuring that the lifting lugsand rails hold up under stress.

• We perform a 100% coil leak test atthe factory. The evaporator andcondenser coils are leak tested at1.4 MPa and pressure tested to3.1 MPa.

• All parts are inspected at the pointof final assembly. Sub-standardparts are identified and rejectedimmediately.

• Every unit receives a 100% unit

run test before leaving the

production line to make sure it

lives up to rigorous Trane

requirements.

Variable Speed Direct Drive

Supply Fan

Efficient, flexible and lowmaintenance direct driven fan

High efficiency fan

Direct transmission, variable speeddrives delivers energy saving through3 aspects :• Higher fan nominal efficiency: The

pulley no longer penalizes theairflow stream at the an inlet,resulting in less turbulence andhigher fan static efficiency.

• Direct coupling drive efficiency:The direct coupling conceptavoids losses by belt friction.Classic belt drive is depletes partof the motor power caused byimproper belt tension, pulley mis-alignment. The direct driven fanimproves motor consumption byabout 15% to 20% compared tobelt driven fan.

• Reduction of power input with fanspeed modulation at part load orin ventilation mode. Substantialenergy savings can be achieved byreducing fan speed by only 20%,resulting in 20% less airflow and50% less absorbed power. On atypical application, the result is anannual energy saving of 30% ofthe total rooftop consumption.

• Power factor of the fan motor iscorrected and inrush current isvery low thanks to progressive fanramp up start (by default: 1minute ramp up time).

Reduced maintenance costs with :• Almost no maintenance direct

coupling compared to belt drive.• Easy commissioning with

adjustment of nominal airlfow andramp up time for progressivetextile duct inflation.

Ease of Installation

Voyager units provide many time andmoney saving features.

Conversionless Units

The dedicated design units (eitherdownflow or horizontal) require nopanel removal or alteration time toconvert in the field - a major costsaving during installation.

Improved Airflow

U-shaped airflow allows for improvedstatic capabilities. The need for highstatic motor conversion is minimizedand time is not spent changing tohigh static oversized motors.

Single Point Power

A single electrical connection powersthe unit.

Single side access

Service technicians can access allmajor components from one side,opening the easy access panels.

Standardized components

• Components are placed in thesame location for all Voyager units.

• One single Unit controller (ReliatelTM) can fit all Voyager models.This provides standardization ofparts.

RT-PRC022-E4 7


Serviceability

Voyager was designed with inputfrom service contractors. Theirinformation helped us design a unitthat would get the service technicianoff the job quicker and save theowner money.

Voyager's Simpler Design

The Voyager design uses fewer partsthan previous units. Since it is simplerin design, it is easier to diagnose.

Micro

• The Micro requires no special toolsto run the Voyager unit through itspaces. Simply press the Test buttonlocated on the right side of thecontrol panel and the unit will walkthrough its operational stepsautomatically.

• As long as the unit has power andthe LED is lit, the Micro isoperational. The light indicates thatthe Micro is functioning properly.

• The Micro features expandeddiagnostic capabilities whenutilized with Trane's IntegratedComfortTM Systems.

• One Zone Sensor option has centralcontrol panel lights which indicatethe mode the unit is in and possiblediagnostic information (dirty filtersfor example).

Easy Access Low Voltage Terminal

Board

Voyager's Low Voltage TerminalBoard is external to the electricalcontrol cabinet. It is extremely easy tolocate and attach the thermostatwire. This is another cost and timesaving installation feature.

Indoor Air Quality• Filters. All rooftops are shipped

with throw-away filters as astandard to be used during the firstdays of operation (usually thejobsite is not completely clean, andhigh efficiency filters would getdirty in a couple of hours, thiswould be a waste of money). Wepropose optional EU4 permanentfilters for regular operation.

• Panels in the indoor air sectionhave a fire-resistant (M0) aluminumfoil-faced insulation. There is nomore insulation particles carriedover by the air. It can be cleanedwhich is particularly interesting forrestaurant applications.

• All our drain pains are sloped. Wethus avoid water stagnation thatgenerates corrosion and micro-organism life such as mold andfungi.

Reliatel Unit Controller Benefits

• Reliatel in the Voyager units hasbuilt-in anti-short-cycle timer, timedelay relay and minimum "on" timecontrols. These controls arefunctions of Reliatel and are factorytested to assure proper operation.

• Reliatel softens electrical "spikes"by staging on fans, compressorsand heaters.

• The Intelligent Fallback or AdaptiveControl is a benefit to the buildingoccupant. If a component goesastray, the unit will continue tooperate at predeterminedtemperature set point.

• Intelligent Anticipation is astandard feature of Reliatel. Itfunctions constantly as Reliatel andzone sensor work together inharmony to provide tightercomfort control than conventionalelectromechanical thermostats.

On dual fuel units (DKD/DKH), Reliatelautomatically selects the best sourceof heat. In low ambient operation,when mechanical heating is notdelivering enough perforamnce, thecompressor switches off and the gasburner delivers heat in optimizedconditions. This result in an optimizedenergy consumption and highercompressor life cyle.

Exhaust Air Options

When is it necessary to providebuilding exhaust?

Whenever an outdoor air economizeris used, a building generally requiresan exhaust system. The purpose ofthe exhaust system is to exhaust theproper amount of air to prevent overor under-pressurization of thebuilding.

A building may have all or part of itsexhaust system in the rooftop unit.Often, a building provides exhaustexternal to the air conditioningequipment. This external exhaustmust be considered when selectingthe rooftop exhaust system.

Voyager™ Commercial rooftop unitsoffer two types of exhaust systems:

1 Power exhaust fan

2 Barometric relief dampers

Application

recommendations

Power Exhaust Fan

The exhaust fan option is a dual, non-modulating exhaust fan withapproximately half the air-movingcapabilities of the supply fan system.

The experience of The TraneCompany is that a non-modulatingexhaust fan selected for 40 to50 percent of nominal supply airflowcan be applied successfully.

The power exhaust fan generallyshould not be selected for more than40 to 50 percent of design supplyairflow. Since it is an on/off non-modulating fan, it does not varyexhaust airflow with the amount ofoutside air entering the building.Therefore, if selected for more than40 to 50 percent of supply airflow, thebuilding may become under-pressurized when economizeroperation is allowing lesser amountsof outdoor air into the building. If,however, building pressure is not of acritical nature, the non-modulatingexhaust fan may be sized for morethan 50 percent of design supplyairflow.

Barometric Relief Dampers

Barometric relief dampers consist ofgravity dampers which open withincreased building pressure. As thebuilding pressure increases, thepressure in the unit return sectionalso increases, opening the dampersand relieving air. Barometric reliefmay be used to provide relief forsingle story buildings with no returnductwork and exhaust requirementsless than 25 percent.

Acoustical Considerations

Proper placement of rooftops iscritical to reduce transmitted soundlevels to the building. The ideal timeto make provisions to reduce soundtransmissions is during the designphase. And the most economicalmeans of avoiding an acousticalproblem is to place the rooftop(s)away from acoustically critical areas.If possible, rooftops should not belocated directly above areas such as:offices, conference rooms, executiveoffice areas and classrooms. Instead,ideal locations might be overcorridors, utility rooms, toilets orother areas where higher sound levelsdirectly below the unit(s) areacceptable.

Several basic guidelines for unitplacement should be followed tominimize sound transmission throughthe building structure:1) Never cantilever the compressor

end of the unit. A structural crossmember must support this end ofthe unit.

2) Locate the unit's center of gravityclose to or over column or mainsupport beam.

3) If the roof structure is very light,roof joists must be replaced by astructural shape in the criticalareas described above.

4) If several units are to be placed onone span, they should bestaggered to reduce deflectionover that span.

It is impossible to totally quantify theeffect of building structure on soundtransmission because this depends onthe response of the roof and buildingmembers to the sound and vibrationof the unit components. However, theguidelines listed above areexperience-proven guidelines whichwill help reduce sound transmissions.

Energy Recovery Module (ERM)

In order to recover heat from exhasutair, it is recomended to use theenergy recovery module. It is placedon the fresh air side of the unit.

In order to satisfy two levels ofefficiency, two technologies areavailable:

- Plate heat exchanger version withan efficiency of 50 to 60%,

- Heat recovery wheel with anefficiency of 60-85%.

The option is available in the twoairlfow configurations: horizontalflow and downflow

The free cooling function is still validwith this option.

The heat recovery wheel version hasan hygroscopic treatment allowingpartial transfer of moisture in parralelto sensible heat.

Clearance Requirements

The recommended clearancesidentified with unit dimensionsshould be maintained to assureadequate serviceability, maximumcapacity and peak operatingefficiency. Refer to the Minimumrecommended clearances Table inthis manual. A reduction in unitclearance could result in condensercoil starvation or warm condenser airrecirculation. If the clearances shownare not possible on a particular job,consider the following:• Do the clearances available allow

for major service work such aschanging compressors or coils?

• Do the clearances available allowfor proper outside air intake,exhaust air removal andcondenser airflow?

• If screening around the unit isbeing used, is there a possibility ofair recirculation from the exhaustto the outside air intake or fromcondenser exhaust to condenserintake?

Actual clearances which appearinadequate should be reviewed witha local Trane sales engineer.

When two or more units are to beplaced side by side, the distancebetween the units should beincreased to 150 percent of therecommended single unit clearance.The units should also be staggered asshown for two reasons:1) To reduce span deflection if more

than one unit is placed on a singlespan. Reducing deflectiondiscourages sound transmission.

2) To assure proper diffusion ofexhaust air before contact with theoutside air intake of adjacent unit.

Duct Design

It is important to note that the ratedcapacities of the rooftop can be metonly if the rooftop is properlyinstalled in the field. A well designedduct system is essential in meetingthese capacities.

The satisfactory distribution of airthroughout the system requires thatthere be an unrestricted and uniformairflow from the rooftop dischargeduct. This discharge section should bestraight for at least several ductdiameters to allow the conversion offan energy from velocity pressure tostatic pressure.

However, when job conditions dictateelbows be installed near the rooftopoutlet, the loss of capacity and staticpressure may be reduced through theuse of guide vanes and properdirection of the bend in the elbow.The high velocity side of the rooftopoutlet should be directed at theoutside radius of the elbow ratherthan the inside.
